【摘要】 于 1999 0 3— 2 0 0 1 0 6对北京东灵山地区鸟类群落进行了研究 ,共发现鸟类 84种 ,依据营巢位置和取食部位的不同可以划分为 6个集团 .对鸟类种群密度、集团丰富度、物种多样性等群落指标与植被结构关系的研究发现 ,地面取食集团的物种数、种群密度与灌木丛的高度和盖度成正比 .影响鸟类密度的栖息地参数对于不同物种存在较大差别 .对地面营巢集团鸟类而言 ,随着灌木高度和盖度的增加 ,鸟类数量明显上升 ;而林冠营巢集团鸟类的数量却随着灌木高度和树种多样性的增加而下降 .鸟类种群密度和均匀度受到灌丛高度异质性和乔木高度的显著影响 ,而鸟类群落的物种多样性则与灌木高度异质性以及乔木密度密切相关更多还原

【Abstract】 The bird communities of Dongling Mountain area were studied from March 1999 to June 2001. Totally 84 bird species are found during the study period. After analyzing the relationship between the vegetation structure and the bird community, the height and cover of the understory are found to have positive correlations between the density and the species number of the ground foraging guild. The heterogeneity of the shrub height and the arbor height influences the density and evenness of the birds significantly, while bird community diversity is correlated with the shrub height heterogeneity and arbor density.更多还原
